On the night of Sept. 6, 2014 NASA's Earth Observing 1 (EO-1) spacecraft observed the ongoing eruption at Holuhraun, Iceland. Partially covered by clouds, this scene shows the extent of the lava flows that have been erupting.

NASA's Earth Observing-1 (EO-1) spacecraft observed Copahue volcano, a 2965 meter high volcano on the Chile-Argentina border, on Jun. 4, 2013. Having recently displayed signs of unrest, the volcano is under close scrutiny by local volcanologists.

On June 14, 2011, NASA's Earth Observing-1 (EO-1) spacecraft obtained this image showing ash-rich volcanic plume billowing out of the vent, punching through a low cloud layer. The plume's grey color is a reflection of its ash content.

NASA's Earth Observing-1 (EO-1) imaged Eyjafjallajökull and identified the extent of a lava flow extending northwards from the main eruption vent. This lava flow is slowly carving its way north through the ice cap.

The Advanced Land Imager onboard NASA's Earth Observing-1 (EO-1) spacecraft obtained this false-color infrared image of Iceland's Eyjafjallajökull volcano on April 17, 2010. A strong thermal source is visible at the base of the Eyjafjallajökull plume.

On Saturday, April 17, 2010, NASA's Earth Observing-1 (EO-1) spacecraft obtained this pair of images of the continuing eruption of Iceland's Eyjafjallajökull volcano. On the left, new black ash deposits are visible on the ground.
